Solutions
Consider the decomposition of
$N _{2} O _{5}$
as
$N _{2} O _{5} \longrightarrow 2 NO _{2}+\frac{1}{2} O _{2}$
The rate of reaction is given by
$\frac{-d\left[ N _{2} O _{5}\right]}{d t}=\frac{1}{2} \frac{d\left[ NO _{2}\right]}{d t}=2 \frac{d\left[ O _{2}\right]}{d t}=k_{1}\left[ N _{2} O _{5}\right]$
Therefore,
$\frac{-d\left[ N _{2} O _{5}\right]}{d t}=k_{1}\left[ N _{2} O _{5}\right]$
$\frac{+d\left[ NO _{2}\right]}{d t} =2 k_{1}\left[ N _{2} O _{5}\right]$
$=k_{1}'\left[ N _{2} O _{5}\right] \frac{+d\left[ O _{2}\right]}{d t} =\frac{1}{2} k_{1}\left[ N _{2} O _{5}\right]=k_{1}'' \left[N _{2} O _{5}\right]$
Choose the correct option.
